Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 120040, here are decompositions:
- 23 + 120017 = 120040
- 29 + 120011 = 120040
- 47 + 119993 = 120040
- 59 + 119981 = 120040
- 149 + 119891 = 120040
- 191 + 119849 = 120040
- 227 + 119813 = 120040
- 257 + 119783 = 120040
Showing the first eight; more decompositions exist.

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 120,040 and was likely granted around 1871.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
